Product Fitment:

2002-2005 Subaru WRX

Engineered for high horsepower and extreme boost pressures, the IAG Fire-Lock Head Gasket System is a purpose-built sealing solution for EJ20 Subaru engines pushing the limits of performance.

Features:

• Developed through years of R&D to combat head gasket failures in extreme builds
  

• Utilizes machined counterbore technology with proprietary alloy fire rings

• Fire rings create a compression seal when torqued, preventing head lift and gasket failure

• Ideal for engines using 14mm head studs and high cylinder pressures

Specs:

• Gaskets made from asbestos-free composite material

• Features silicone beading around oil and coolant passages for enhanced sealing

• Fire rings crafted from an IAG-specific heat-treated alloy for maximum durability

• 93.5mm bore with .051" thickness for precise fitment and performance

Required Components & Fitment:

• Requires use of IAG ARP 14mm head studs for proper torque and sealing

• Gaskets are sold in pairs, includes (4) Fire-Lock rings

• Designed for high-boost, high-compression, and track-ready EJ20 builds

• Machine work required: counterbore must be machined into block deck surface

Installation Notes:

1. Any previously o-ringed blocks or heads must be filled and resurfaced

2. Fire-Lock gaskets require substantial clamping force; only compatible with 14mm head stud systems

3. Blocks previously honed may need to be overbored to the next size

4. Head resurfacing required during future servicing due to ring impressions
